' BUILDING consrnnc'rron.

Application filed March 28, 1927, Serial No. 179,053, and in Great Britain November 13, 1925.

This invention relates to the construction of buildings and other structures of concrete slabs (armoured or'not), and it'has for its object to simplify and expedite their instal' lation or erection whilst providing for good and permanent access or circulation of air for preventing condensation.

The type of construction to which the invention more particularly relates is that in which tongued and grooved slabs, panels, blocks, orthe like, previously cast to the desired shape, are secured to concr'ete uprights or standards.

; According to'the invention, a wall construction comprises tongued and grooved slabs, panels, blocks, or'the like, which are bonded to concrete uprights or standards 7 and have the grooves in the upper edge formed with an auxiliary groove or channel to receive means for securing or bonding them to the uprights. Further, concrete sills, on which rest the bottom course of slabs and the uprights or standards, are provided with continuous grooves, one of which receives tenons on the uprights, and a smaller groove, which receives tongues on the slabs, and with air-ducts which allow air to enter from the outside and circulate within the .wall. The upper ends ofthe uprights have tenons which similarly engage a continuous groove in a concrete wall-plate.

The invention also comprises other features whereby the various parts of the construction are firmly secured together.

And in order that the invention may bereadily understood, it will now be fully described with reference to the. accompanying drawings, which show, by way of example, a building construction employing the new slabs or the like.

Figs. 1 and 2 are a'cross section and a a good fillingor grouting to hold the parts together. I

' f and 9 represent tongues and grooves or channels, which serve to connect the facing slabs or panels together, and to the foundation sill a.

hyrepresents the additional channel or groove in the slab b, and h theirecesses 1n the standards'or uprights 0 into Whichengage the bent down ends of metal ties, dogs,

' oriclamps i, which are embedded in cement mortar. The back of the recess h in the face of the standard may be partly arched or curved as shown, to facilitate the insertion of the tie, dog, or clamp. That portion of the standard 0 in which the ties are held, is reinforced by an iron rod 0 for the purpose of imparting greater strength. to the structure.

k is an airduct, pocket, or opening, which extends downwards from the channel or groove 9 and then opens at the back of the foundation sill a.

In the arrangement shown in Fig. 3, for supporting the flooring joists, a wall-plate or beam a is arranged between the top of one set of standards a and the bottom of the next set to form a bridge or bearing to support the ends ofthe wooden floor joists Z.

These Wall-plates or bearers are provided with reinforcement m, and also with air openings or ventilating ducts 7:

As before, 6, 0 represent facing slabs and z the ties or clamps for locking them to the standards.

The reinforcing rods m in the standards may be allowed to project into the wallplates or beams, as shown at m to assist in locking them together. 7

In the arrangement shown in Fig. 4, the window sill a is'provided with an additional groove or channel m to receive the bottom flanges of the window frame n. The facing slabs and standards are indicated by the same-letters as in the other figures whilst' 0 indicates theinterior wall-lining and p the sill The concrete stamlards may be cast in suitable sizes and lengths for convenient manipulation andto suit the Work in view. They may also have tenons or lugs at their top ends to fit into the sills or slabs (L2.

Suitable air passages or ducts, like those shown in Fig. 2, are provided, where necessar to allow entry of air between the outer Wu 1 of the structure and the finished lining; which may be lath and plaster, or other suitable material.

The foundation footing a, may also he formed with air passages or duets, below the damp course, to allow ventilation throughout the structure,and to prevent condensation, as well as drysrot in the Wood on flooring and joists.

The wall-plates may be omitted, and a shoulder, or shoulders may be cast on the standards to receive the ends (if the joists at the floor levels.

Having now described my invention what I claim is 1. A well construction, including uprights slabs provided with tongue: and grooves on the edges thereof, cooperating means in the upper edges of lLl'lQHSlltllSdllltl in the up rightswto bond the slabs to said uprights, said lastmeuns including a groove 1 orn1edin (lotion, a sill mounted thereon and provided with an air duet and two continuousgrooves, said grooves being in its upper face, tongue andsgrooved uprights and slabs, each having its tongue titted in the respective groove of the silhiand 111811115; for bonding the slabs to the upriglns.
